I am a Co-Founder at Diffeo working on collaborative intelligence problems using machine learning. As a part of Diffeo Labs, I am thinking about how the tools and perspective from theoretical physics can be applied to artificial intelligence.

More broadly, I am interested in the interplay between physics and computation. My work in theoretical physics has focused on the relationship between black holes, quantum chaos, computational complexity, randomness, and how the laws of physics are related to fundamental limits of computation.

Theoretical Physics

Some of my work focuses on what happens when something falls into a black hole (in anti-de Sitter space). The black hole will very quickly scramble (but not destroy) the information. Black holes are thermal systems, and this is actually a manifestation of the well-known butterfly effect. We can try to think about this process in terms of its computational complexity, or we can study it as a distinguishing feature of quantum chaos.
